3x4 - The Nightmare Neighbour Next Door

In Shropshire, a man moves in to his parents' home to help put a stop to a neighbour's harassment, but events escalate into violence. In Essex, a mother and her daughter find what seems to be the perfect house, only for their lives to be made a misery after they object to a planning application for an extension. Two elderly residents who feel they are the victims of noise from next door have to deny any wrongdoing themselves when the police arrive on their doorstep.
